Steel

Carbon Steel

The most economical of all the steel choices, carbon steel is often machined into parts and used in structural applications. It includes low-carbon steel, as well as alloys 1045, 1117, 1144, 12L14, and 1215.

Alloy Steel

Stronger and harder than carbon steel, alloy steel is preferred for high-stress applications, such as axles, torsion bars, and drive shafts. It includes alloys 4130, 4140, 4340, ES2100, and 8620.

Other Metal Square Tubing

Multipurpose Aluminum

Striking a good balance of corrosion resistance and strength, these 6000-series aluminum alloys are also heat treatable, machinable, and weldable. Theyâ€™re widely used for vehicle parts, door frames, and rail-framing systems.

Stainless Steel

With a minimum of 10% chromium content, stainless steel is known for corrosion resistance. It's typically not as strong as steel and can be more difficult to machine.

Ultra-Formable 260
Brass Rectangular Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but itâ€™s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.
